Trying to repair a game gear
Post Posted: Sat Mar 21, 2020 11:45 pm
Hi all, I picked up a 2nd Game Gear at the swap meet recently and its giving me a ton of problems. I've already replaced the 12 capacitors on the board, and on the power and sound boards. However, the system still isn't working.

On batteries, it won't turn on at all. The power supply does work, I tested it in my other GG.

When plugged in, it will turn on for a second and then turn off. Sometimes it will stay in longer, but I get a white screen with horizontal blocks that travel down the screen.

Any ideas? I'm sorry If this was covered in another thread, I searched but couldn't find the same problem.

That still sounds like a capacitor issue. Check over your work and be sure none of the caps have been soldered in backwards.

Thanks for the reply. I suspected there wasn't any other option. I rechecked and replied the solder on all the capacitors and still no luck. This one may be beyond my skillset to repair, if it's even repairable.
